How to make an ELMAH report on errors

I am using https://booking.pronestor.com/Booking.NET/Calendar.mvc as an example

• Shorten the link to https://booking.pronestor.com/
• add elmah.axd at the end https://booking.pronestor.com/elmah.axd 

you have opened the elmah and can collect error data

For on-premise installations, you can find the elmah log in your Pronestor installation. The default path would be

D:\Webdata\Default Website\YOURSITENAME\App_Data

The file is Elmah.db
